Mailman Cross-Site Request Forgery (CSRF) Vulnerability - CVE-2021-42097
GNU Mailman before 2.1.35 may allow remote Privilege Escalation. A csrf_token value is not specific to a single user account. An attacker can obtain a value within the context of an unprivileged user account and then use that value in a CSRF attack against an admin (e.g. for account takeover).
